<p>New technology could tip the balance back in favor of some solar-panel manufacturers outside China.</p><p>Chinese solar-panel manufacturers dominate the industry, but a new way of making an exotic type of crystalline silicon might benefit solar companies outside of China that have designs that take advantage of the material.</p>Mon, 21 Nov 2011 05:00:00 +0000digitalservices426162 at http://www.technologyreview.comQuantum Dots as Solar Cellshttp://www.technologyreview.com/news/423528/quantum-dots-as-solar-cells/
<p>N-type and p-type semiconductor nanocrystals could pave the way for new types of solar cells.</p><p>The key to using silicon in electronic devices such as transistors and solar cells lies in doping, or adding in small quantities of other elements, to create an excess of electrons (n-type) or positively charged holes (p-type) that change the material’s conductivity. N-type and p-type silicon are butted together to form p-n junctions, the basic building blocks of electronic devices such as solar cells, light-emitting diodes, and transistors.</p>Mon, 04 Apr 2011 04:00:00 +0000digitalservices423528 at http://www.technologyreview.com
